How to update previews after editing original photoshop file?

New to lightroom- old bridge user.

I've edited several psd files via Lightroom using "edit photo with PS", "Edit Original" and when I save and get back to Lightroom, the previews aren't updated.

If I press space to see a larger preview, then zoom back out it's updated...

How can I fix this? 

Also, how can I tell what type of preview I'm seeing (smart vs. non smart).

    What you describe is expected behaviour. Also, since Lr7.0 was released the preview update behaviour was changed so that it occur in background during idle time.

    There are badges displayed in lower segment of Histogram. This Help document shows the various badges indicating whether original and/or smart preview is available/in use How to use Smart Previews to view and edit photos in Photoshop Lightroom Classic CC

    Thanks.  Is there a way to change the behavior?  i.e. have it run every x minutes or instantly...

    You can't change the idle time behaviour. However, you can force Lr to build/update a preview or multiple previews from the Library > Previews menu. Typically, it's more efficient to do as you described above for individual photos and use the build previews option when multiple photos are involved


    Actually, I think there may be a bug...

    I edited a psd files via Lightroom using "edit photo with PS", "Edit Original" and all I do is hide a layer with a watermark.  I then save and get back to Lightroom, the previews aren't automatically updated.

    I select the photo and do Library > Previews> Update (tried both 1:1 which is supposed to update everything, and standard) then I get a "no files to update" and I still see the watermark.

    I tried deleting the 1:1 preview, but it doesn't seem to delete it as when I try to update it it still states there is nothing to update.  Even zooming in doesn't work!

    After a few minutes the preview is correct.  I also observed this behavior when making more serious edits which is a royal pain...

    HELP!

    To answer your second question first: You are always viewing normal previews. 'Smart preview' is a misleading name. It's not a preview at all. It is a small DNG that serves as substitute for the original when that original is offline. 'Smart Proxy' would have been a much better name.

    To update the normal previews if they don't update automatically, select them all and then choose 'Library - Previews - Build Standard-sized Previews'.
